I was (likely) targeted by North Korean hackers, so I found the payload and reverse-engineered a security tool.
A recruiter contacted me on LinkedIn on Wednesday. CEO of a crypto startup, $125/hr advisory role, review our product via GitHub repo as the first interview step. The social engineering was top-notch, polished profile with 500+ connections, days of back and forth DMs, the cracks only appeared in hindsight. Friday, I got access to the repo, which felt like a win. With a healthy amount of skepticism, I reviewed the repo with Claude. The codebase looked professional and complete, the README was well structured, and the .json files where malware would normally be hidden came back clean. The payload was buried well enough that Claude and I missed it. Luckily, I decided to enjoy my Friday night and not clone the repo. This is the main reason I want to share my story here: many of us are starting new businesses, and when someone offers you a paid role that seems like the perfect fit, your judgment becomes clouded. I know mine did.Having had more time to think, the inconsistencies started to surface. Lying in bed around midnight on Saturday, the eureka moment happened. This was definitely an elaborate scam. I stayed up all night digging through the repo and gathering evidence to file reports. Here’s what I found: The repo contained a fully operational malware delivery chain: - .vscode/tasks.json configured with runOn: folderOpen — silent code execution the moment you open the folder in VS Code, zero prompt. - .githooks/post-checkout buried under 40 lines of decoy comments, downloading and executing a remote payload from a Vercel server across Mac, Linux, and Windows simultaneously, all output suppressed. - Private key social engineering via the .env.local README instruction, a backup vector in case the malware delivery fails or gets caught  - This is a complex attack chain designed to pass pre-clone inspection. Once you clone it, you’re cooked. I stayed up all night gathering evidence and filing reports: Vercel - both domains, GitHub - account + repo, LinkedIn profile, Basescan wallet flagged, Neynar/Farcaster. Then the big guns: RCMP/CAFC and FBI IC3. But then I started thinking, what tools should I have used to protect myself in this situation?

@Kurt Henninger Thanks for the star, really appreciate it! And that's a great point, the last thing I do before pushing is have Kimi scan for PII and secrets. Sounds like we're on the same page there. Hadn't thought about it as a repo-guard use case but it's worth considering.

Thanks everyone for the kind words, questions, and GitHub stars! Didn't expect this kind of response overnight. If you starred the repo, feedback on the tool itself is always welcome. Happy to keep answering questions as they come in. Stay safe out there!
New Video: We Audited a Vibe Coded Production App. Three Holes Found.
Dropped a new one for you all. Mike from Urban Pulse let me share footage from his security audit. He vibe coded his whole platform using my routing architecture, then hired me and my team to read every line before he opened it up to high ticket clients. We took our time over many hours. We found three holes that I share here. A Google Maps API key that had already been flagged and locked down by Google. A second cryptographic auth layer the AI built on top of Supabase, which already handles all of this for you. A JWT verification step that never checked the issuer, meaning any valid Supabase token from any project on the internet would have passed. This is what real building and shipping looks like in the AI world. Mike built something that used to take a year and a couple hundred grand. He did it solo. Then he paid engineers to audit it before any customer touched it. Copy his move. If you are vibe coding anything you plan to put in front of paying clients, watch this one.

@Gloria Kate Solo tool for now, open source, built it for the community more than anything. If it gets traction there's a natural path to a broader pre-clone security layer; private repo scanning, contributor network analysis, maybe a GitHub Action that runs on PR. But right now I just want developers to have something they can actually run before they open a stranger's repo. The gap was real, the attack was real, the tool needed to exist. Everything else is secondary. Really appreciate your interest though as I'm very new to all of this.

@Gloria Kate Absolutely! Any tips would be greatly appreciated
Welcome to Clief Notes. Here's where to start.
1. Watch the intro video and introduce yourself in the intro post here 2. Start with The Foundation (free course). Concepts, folder architecture, prompting framework. Everything else builds on this. 3. Check in at the bottom of each lesson. Polls, discussion posts, other members working through the same stuff. Use them. 4. When you're ready to build real things, move to Implementation Playbooks (Level 2). When you're ready to build your own tools, Building Your Stack (Level 3). 5. Post your work. Ask questions. Help others when you can. What are you here to build?

hello, here because Jake's youtube content is lightyears ahead of the rest! Have been building with AI for about a month now, but entirely on my own, and feel it is time to circle back for some guidance. Stoked!
